Solar Thermal Deserves Our Support
| May 13, 2012 | Posted by Craig Shields under Solar Thermal |
Here’s a good article on a recently completed solar thermal tower (aka concentrated solar power or CSP) in the desert between Las Vegas and Reno, NV.
The thing to like about solar thermal, as we’ve often discussed here, is that it affords us a fairly low-cost way of storing energy and delivering it when the sun isn’t shining. This is due to the fact that in today’s world, we can store heat energy (in vats of molten salt) far less expensively than we can store electrical energy (in batteries). Thus solar thermal installations can be treated as baseload, delivering power on a consistent 24X7 basis.
That’s the good news. Read More
What’s the Plan For Phasing Out Fossil Fuels? Which Do You Want To Hear First? The Good News or the Bad News?
| April 29, 2012 | Posted by Craig Shields under Fossil Fuels |
Germany has installed enough photovoltaics that, at this point, coal-fired power plants are beginning to become unprofitable. This is driven by a combination of factors, e.g., that coal isn’t asked to provide power at the peak of the day, when both the sun and the price of electricity are at their zenith. Of course, most of us cheer when coal runs into trouble, but issues like this raise some fantastically interesting questions about the future of power generation – and transportation – as we migrate from fossil fuels into more sustainable modalities.

You’ll Never See Another Nuclear Power Plant Commissioned in the US
| April 14, 2012 | Posted by Craig Shields under Nuclear |
Frequent commenter/author Frank Eggers writes on my piece on subsidies for nuclear:
Nuclear power has been demonstrated to be far safer than fossil fuel power. Coal plants cause health problems that, while severe, are difficult to pinpoint because generally they simply greatly increase the health problems which would exist anyway whereas nuclear accidents, though infrequent, have a more concentrated and obvious effect.
Frank: I’m not one of the hysterical anti-nuke people who grossly over-estimates the danger. Having said that: Read More
Integrating Large Amounts of Wind Power Onto the Grid
| April 7, 2012 | Posted by Craig Shields under Wind Energy |
I wrote a piece a few months ago on nay-sayers to wind, in which I pointed out that the UK’s Duke of Edinburgh just may be the king. In it, I noted:
Here in the U.S., we have climate change deniers, and all manner of other opponents to renewable energy. In essence, they’re the oil and coal companies, the members of Congress they influence, and those who believe the torrents of propaganda they generate on “clean coal,” “safe nuclear,” and the other oxymorons that are creeping into our vocabularies.
In the U.K. however, they come in the form of certain members of the nobility. Read More
Replacement of Diesel with Solar Can Be Complicated
| April 7, 2012 | Posted by Craig Shields under Photo-voltaics |
Here’s a wonderful discussion that illustrates how an apparent no-brainer in terms of the replacement of diesel with solar on an island nation (Anguilla) can become a complicated mess.
In particular, the chairman of the Anguilla Renewable Energy Office says, “As we all know, you can’t store electricity, it has to be used when it is generated.” (They need a new chairman.) Also, per a local solar consultant: “(where) Jamaica, St. Lucia, Greneda, and other islands have implemented net-metering in some form, Anguilla has not. This means that you can have solar, but you cannot interconnect it with the grid. All the developed countries of the world incentivize solar, Anguilla outlaws it.”
Yep, that’s a mess all right.
Are Electric Vehicles Really a Boon to the Environment?
| March 12, 2012 | Posted by Craig Shields under Electric Vehicles |
There are at least two kinds of “EV deniers” (as I call them), i.e., people who doubt that electric vehicles represent an improvement for the environment over gasoline. The first concept is that for the foreseeable future, an increase in the electric load means burning more coal. I.e., coal plants that would otherwise have been tamped down during off peak hours are instead running full-throttle through the night. Frequent commenter Glenn Doty points out that even California and the other states that have no coal buy power when they need it, and this ultimately means that somewhere, more coal is being burned.
Classically, I’ve addressed this by saying that we do indeed face the need to shut down coal plants; this is part of the reason that I favor a significant role of government in support of the migration to renewables and the ancillary areas: smart-grid, efficiency, conservation, energy storage, etc. I’ve also pointed out that the true externalities of fossil fuels are almost completely ignored in most of the arguments. E.g., as bad as coal is, it could be argued that it’s not as bad as oil because of international security issues. The costs (both financial and human) of war, terrorism, and civil unrest and injustice are enormous, and normally totally dismissed. As oil becomes scarcer, these problems will only get worse.

Book Launch: “Is Renewable Really Doable?”
| February 29, 2012 | Posted by Craig Shields under Renewables - Business |
It’s time to launch my second book, Is Renewable Really Doable? on Amazon.com. The big day: March 15, 2012. I hope you will mark your calendar, and buy the book on that date.
To help generate interest in the subject, we have a giveaway: a hot new report called “Insights in LCOE – The Levelized Cost of Energy,” by industry analyst Mike Hess.
Before our society can decide on a certain course for its energy policy, we need to ask ourselves a central question: What Does It Cost?
Here’s a 32-page study, dealing with tough questions about land use, externalities, the safety of fracking, food and water shortages, climate change, transmission rights, smart-grid, efficiency, conservation, consumer incentives, carbon taxes, energy storage, health hazards, feed-in tariffs, subsidies – you name it.

Must Eco-friendliness Come at the Expense of the Economy?
| February 8, 2012 | Posted by Craig Shields under Renewables - Business |
Here’s a wonderful article that gets at an issue I come across constantly: the implication that environmentalism and job growth are opposed to one another. Considering we have the option to put literally millions of people back to work in renewable energy, energy storage, electric transportation, smart-grid, etc., I’m always stunned when I hear politicians peddling the idea that eco-friendliness must come at the expense of the economy.
Electric Vehicles and CO2 Emission Abatement
| December 22, 2011 | Posted by Craig Shields under Electric Vehicles |
Frequent commenter Glenn Doty writes:
What would really be nice is an infographic comparing the cost of mitigating CO2 with various alternatives… just to put the different alternatives into proper perspective.
For instance, how much more does it cost to abate CO2 emissions by setting up a rooftop solar panel in NJ as compared to installing additional insulation in an office building in Texas or setting up a wind farm in the Dakotas?
This would be extremely instructional to your readers in terms of what policies would make more sense… and it would be fun to look at how you graph the negative CO2 abatement value of EV’s.
I respond:
Ha! I was reading along here, wondering when you were going to make your point about EVs, and lo! (a good word for the season), there it was.
Seriously, please send me a high-level treatment of your reasoning.
At a minimum, there are two things I don’t get. Read More
